INTRODUCTION

Your GME TX3350 80 channel radio is Australian designed
and built and is the most advanced UHF Citizen Band radio
available. It combines the very latest in electronic hardware
with the most up-to-date computer aided design and
manufacturing techniques to produce an extremely compact
mobile radio with outstanding specifications and performance.
The SoundPath™ speaker control mic brings you clear sound
and total control from the palm of your hand, allowing your
radio to be mounted almost anywhere in your vehicle.

IMPORTANT INFORMATION

CONCERNING UHF CB RADIO
The use of the Citizen Band radio service is licensed in
Australia by the ACMA radio communications (Citizens
Band radio stations) Class Licence and in New Zealand by
the Ministry of Economic Development New Zealand (MED).
A General User Radio Licence for Citizens Band radio
and operation is subject to conditions contained in
those licences.
The class licence for users and equipment operating in the
CB/PRS 477 MHz band has been amended. This radio meets
the new 80 channel standard.
In simple terms the same amount of spectrum is available;
however, radio transceivers can now operate in a
narrower bandwidth and hence use less spectrum. These
radios are generally referred to as narrowband or 12.5
kHz radios. By using 12.5 kHz channel spacing instead
of 25 kHz, the 40 channels originally allocated can now

be expanded to 80 channels thereby doubling the channel
capacity and relieving congestion in the UHF CB/PRS band.
Original 40 channel wideband Radios will continue to
operate on the original 40 channels, however they will not
be able to converse on the newer channels 41 – 80. The
newer narrowband radios will be able to converse with all
older 40 channel wideband radios on all channels 1 to 40 as
well as the newer channels allocated from 41 to 80.
The mixing of narrowband and wideband radios in the
same spectrum can cause some possible operating issues
of interference and varying levels of received volume.

POSSIBLE ISSUES

When a new narrowband radio receives a transmission from an
older wideband radio the speech may sound loud and distorted –
simply adjust your radio volume for best performance.
When an older wideband radio receives a signal from a new
narrowband radio, the speech may sound quiet – simply
adjust your radio volume for best performance.
There can be interference from a nearby transmitting radio if it
is using a channel adjacent to the channel you are listening to.
Simply try going up or down a few channels from the currently
selected channel. The above situations are not a fault of the
radio but a symptom of operating wideband and narrowband
radios in the same bandwidth. This possible interference will
decrease over time as the population of wideband radios ages
and decreases.

EMERGENCY CHANNELS

The ACMA has allocated channels 5/35 for emergency use
only. Channel 5 is the primary Simplex Emergency Channel.
Where a Channel 5 repeater is available, you should select
Duplex on CH 5.
NOTE: Channel 35 is the input channel for the Channel 5
repeater therefore Channel 35 should also not be used for
anything other than emergency transmissions.
